This still has problems.  For example see the idl below.
Also note that this is the cause of the warnings in httpresquest.idl .

Huw.

import "objidl.idl";
[uuid(12345678-0000-0000-0000-000000000000)]
library foo
{
    typedef [uuid(12345678-9ab0-0000-0000-000000000000)] struct f {int x;} f;
    [uuid(12345678-9abc-0000-0000-000000000000)]
    interface IMy : IUnknown
    {
        HRESULT foo([in]f *ptr);
    }
}
